Question: Draw the structure for each compound using wedges and dashed wedges.
The following is the structure of compounds using wedges and dashed wedges:
cis-1,2 dimethyl cyclopropane
Wedges and dashed wedges are used to represent the structures of stereoisomers. Stereoisomers are compounds with the same molecular formula but different three-dimensional arrangement of their atoms.
In the case of cis isomers, both functional groups are present on the same side of the molecule. On the other hand, in the case of trans isomers, both functional groups are present on the opposite sides of the molecular plane.
In the structure of cis-1,2, -dimethyl cyclopropane, both methyl groups are present on the same side of the molecule, as shown in the following structures. Dashed wedges imply that both methyl groups are present below the plane of the molecule.
The wedges indicate the presence of both methyl groups above the plane of the molecule, as shown in the following structures.
Cis-1,2 dimethyl cyclopropane
In the trans structure, both alkyl groups are present on the opposite side of the molecule. One of the alkyl groups will be above the plane, and the other will be below the plane, as shown in the following structures:
Question: Consider the substituted cyclohexane shown in the ball-and-stick model.
